Abstract
In a developing cartridge, a developing roller extends in a first direction. A developing roller gear, a coupling, and first and second idle gears are positioned at an outer surface of a casing. An agitator gear has an end face in the first direction facing the outer surface. A first protrusion is positioned between the end face and the outer surface, and at a position outside of addendum circles of the developing roller gear, coupling, and first and second idle gears. The first protrusion is pivotally movable about an axis extending in the first direction between a first position and a second position. A first protruding portion has, at the first position, a first length in a second direction connecting the developing roller and the first protruding portion, and has, at the second position, a second length different from the first length in the second direction.
